Properties of the plastics

The main properties of all fluoroplastics are chemical resistance, UV resistance, low frictional resistance, high heat resistance and excellent electrical insulation. Fluoropolymer hoses and profiles are ideal for chemical, electrical, mechanical, automotive and heat exchanger applications. The main difference within fluoroplastics is that PTFE, unlike all other materials, is not a thermoplastic material. PTFE cannot be vacuum formed, conventionally extruded or injection molded.

PTFE Polytetrafluoroethylene

The unique properties of PTFE have made it the polymer of choice for many applications. PTFE is used in many products, such as advanced medical devices and high-temperature industrial equipment, due to its low coefficient of friction for a polymer and extremely wide operating temperature range. Unrivaled chemical resistance and extreme chemical inertness have made PTFE the first choice among plastics for the chemical and analytical industries.

FEP Fluoroethylene propylene

Although FEP is similar to PTFE in its properties, it also has some significant differences. It has a slightly higher coefficient of friction, a lower continuous operating temperature and is more transparent than PTFE. FEP also offers lower gas and vapor permeability and excellent UV resistance

PFA Perfluoroalkoxy

PFA was developed to increase the continuous operating temperature of FEP resin. Melt processability allows PFA to be processed in longer continuous lengths than PTFE.

PVDF Polyvinylidene fluoride

PVDF is often referred to by one of its trade names, Kynar®. It was primarily developed for applications that required excellent chemical resistance, high purity levels and superior mechanical properties. PVDF is often used as a lining or protective barrier in chemical applications.

THV Tetrafluoroethylene Hexafluoropropylene Vinylidene Fluoride

THV offers high chemical resistance, high flexibility, low application temperatures and excellent transparency. THV can be radiation cross-linked using an e-beam and can be used in multilayer constructions. It has outstanding permeation resistance to highly aggressive media and chemicals. THV offers excellent optical clarity and transmission, especially in the UV and visible parts of the solar spectrum. THV is easier to bond to other plastics and elastomers than the other fluoroplastics.
